Description

  The present invention relates to a frequency therapy device.

  As shown in Patent Document 1, a pair of electrode pads that can be in contact with the human body with the affected area in between, and the direction is reversed between the pair of electrode pads at regularly repeated time intervals, alternately A frequency therapy device is disclosed that includes a controller configured to flow a current having a voltage waveform in which the voltage increases or decreases on the positive side and the negative side.

  In this type of frequency therapy device, it is also known to sequentially apply a plurality of voltage waveform currents having different frequencies to the affected area. In this case, the current waveform is applied for a certain period of time by repeatedly using the same waveform for each type of voltage waveform.

  In a conventional frequency therapy device, a voltage waveform is formed for each frequency, or waveform data stored in a waveform memory is read out, and the data is converted into an analog waveform by a D / A converter to obtain a predetermined waveform. Has been output.

  In this case, the voltage waveform or waveform data is a digital waveform generated by PWM. Compared with the case where the analog waveform is used as it is, the spiked portion of the rising and falling portions is the number of digitized bits in the digital waveform. Although depending on the sampling frequency, the spike portion disappears particularly when the wavelength is shortened.

  Since the spike portion has been conventionally regarded as noise, there is no problem as long as it is, but recently, in the frequency therapy device, when the voltage is higher, the impact given to the human body becomes larger, and the greater this impact, for example, It is said that the pain relieving effect is great.

  In general, when the rising spike and the falling spike are reproduced with digital waveforms as described above, a problem arises in that the signal to be handled becomes large and the element has to be enlarged.

  In addition, when currents having a plurality of voltage waveforms having different frequencies as described above are sequentially applied to the affected area, a current of a certain type of frequency is applied to the first affected area, and then the electrode pad is attached to another part of the human body. In this case, the patient may not be able to re-apply by himself / herself, and the nurse or caregiver may not be able to re-apply the current. There is a problem that the burden on nurses becomes large because they are forced to ask each time.

  The main unit 20 sequentially reads out a waveform memory 22 in which a plurality of voltage waveforms having different frequencies are stored, and a plurality of types of voltage waveforms stored in the waveform memory 22, and makes a pair of currents of the voltage waveforms. And a central control device (hereinafter referred to as CPU) 40 that flows between the electrode pads 12 and 12.

  The waveform memory 22 stores a voltage waveform as waveform data formed with a sampling frequency of 192 kHz or more and a quantization bit number of 24 or more for each of a plurality of types of frequencies (details will be described later).

  The CPU 40 reads out the waveform data for each one type of frequency from the waveform memory 22 and outputs the waveform data to the D / A converter 24 for a preset time for the one type of frequency. The voltage is converted into a waveform, and the current of the voltage waveform is configured to flow between the electrode pads 12 and 12.

  In addition to the waveform memory 22 and the D / A converter 24, the main body unit 20 includes an output drive set 26 including a pair of output drives 26A and 26B, a DC / DC converter 30, a regulator 32, a notification sound output system 36, A negative voltage control unit 38 is provided.

  The D / A converter 24 performs D / A conversion on the waveform data read by the CPU 40 from the waveform memory 22 at a sampling frequency of 192 kHz or more and a quantization bit number of 24 or more, and outputs the analog waveform to the output drives 26A and 26B. Have been to.

  The output drives 26A and 26B are configured to change the output from the DC / DC converter 30 based on the analog waveform and output the output to the electrode pads 12, 12 and 14, respectively.

  The CPU 40 is a mode in which the output drives 26A and 26B from the display control touch panel 16C and the panel operation switch unit 16B are simultaneously operated, a mode in which the other is continuously operated after the end of one operation, or the other is repeatedly repeated a set number of times. Thus, a command signal that is in a mode operated by the same code can be output to the output drives 26A and 26B.

The amount of electrons that enter is greater than the amount of electrons that flow out of the body, thereby suppressing the influence on the human body due to the shortage of electrons. Here, the reason for setting it to 5% or more is that even if the power supply voltage fluctuates, the shortage of electrons in the human body can be suppressed, and the reason why it is set to 10% or less is to suppress excess electrons.

The voltage waveforms of N types of frequencies are stored in any one of the waveform storage areas 22-1 to 22-N for each type.

  FIG. 4 shows an example of the recording state of the voltage waveform in each waveform storage area of the waveform memory 22. FIG. 4 schematically shows voltage waveform states of four types of frequencies of 20 Hz, 880 Hz, 5 kHz, and 10 kHz belonging to the code number 1231, for example.

  In each of the waveform storage areas 22-1 to 22-N of the waveform memory 22, voltage waveforms having the same frequency and the same waveform are stored continuously and repeatedly for 3 minutes. Yes. For example, when the frequency is 20 Hz, 3 (minutes) × 60 (seconds) × 20 = 3600 identical voltage waveforms are repeatedly stored. The distance between the voltage waveforms is constant, so that there is no overlap or separation between adjacent waveforms.

  Each voltage waveform is basically in the state as shown in FIG. 5 and is represented by a digital signal which is represented by 24 quantization bits and a sampling frequency of 192 kHz, and is divided into reciprocal times of the sampling frequency.

  In this embodiment, two output drive sets 26 are provided, and the CPU 40 selects an output channel with the output channel selection button 17H, and for each of the first output channel and the second output channel, with the code setting button 17G, A different code is set, and, of the two output drives 26A, 26B, for example, first, direct current is supplied only to the output drive 26A. After the supply of direct current by the output drive 26A is completed, the other output drive 26B is supplied. It is comprised so that direct current can be supplied.

  Next, with reference to FIG. 6, the process of treating with the frequency therapy device 10 according to the above embodiment will be described.

  First, when the power switch 17D is turned on in step S101, the display / operation switch unit 16 is turned on in the next step S102, and the code number display unit 17A in the display unit 16A is in a state where a treatment code can be set.

  In step S103, the output channel selection button 17H is operated to sequentially select the output drives 26A and 26B, and then a 4-digit treatment code is set on the display control touch panel 16C by the code setting button 17G for each selection code (output) A treatment code may be set only for the drive 26A).

  As a result, the code group voltage waveform reading means 47 is activated, and one by one from one of the waveform storage areas 22-1 to 22-N in the waveform memory 22 based on the signal from the corresponding frequency order storage means 56 for each code. The waveform of the frequency of the first, second,..., As the voltage waveform of the nth frequency can be read out based on the stored order.

  In the next step S104, the voltage waveform of the first frequency is selected, and the voltage waveform stored in, for example, the waveform storage area 22-2 in the waveform memory 22 is read out. In this waveform storage area 22-2, voltage waveforms for 3 minutes are continuously stored. In the next step S105, when the start switch 17E is turned ON, in step S106, the first frequency voltage waveform is stored. Thus, an analog output is generated from the output drive 26A.

  Immediately after the pulse is generated, in the next step S107, the output intensity shown on the intensity display unit 17B in the display unit 16A is changed to, for example, the part of the electrode pad that has touched the patient by operating the strength button 17F on the display control touch panel 16C. Adjust the output intensity so that no pain occurs.

  The analog output corresponding to the voltage waveform of the first frequency continues for 3 minutes, but when the treatment is interrupted for some reason, the start switch 17E is activated by the IR remote control transmitter 18, and this becomes an interrupt switch. In step S108, Yes is selected, and in step S110, the analog output is returned to zero. At the same time, an announcement voice “I will suspend” is output from the speaker 36C.

  If the interruption switch is not turned on during the three minutes, the result is No in step S108, the process reaches step S109, and the output returns to zero after 3 minutes of analog output generation time.

  On the other hand, when the start switch 17E is operated by the IR remote control transmitter 18 after the output is returned to zero by the interruption switch ON, this is the restart switch ON, Yes in step S111 is selected, and the process returns to step S106. If No, the process returns to step S111.

  In the next step S112, an analog output is generated with the selected second frequency voltage waveform.

  As in the case of the first frequency voltage waveform, the output intensity is adjusted in step S113, and it is determined whether or not the interruption switch is ON in step S114. If Yes, the process proceeds to step S116, and the output returns to zero. If Yes in step S117, the process returns to step S112. If No in step S117, the process returns to step S117.

  If the interruption switch ON is No in step S114, the process proceeds to step S115, and returns to zero after 3 minutes from the generation of the analog output due to the second frequency voltage waveform. In the next step S118, the above steps S106 to S111 are repeated for the third to nth frequencies, and after an analog output is generated for 3 minutes for the nth frequency, the process proceeds to step S119.

  In step S119, it is determined whether or not the next treatment code is set. If No, the process proceeds to step S120, and the end lamp buzzer is turned on, that is, the treatment is terminated from the speaker 36C in the notification sound output system 36. The patient or the assistant is informed by the patient and turns off the power switch 17D, and the process ends in step S121.

  When the output of another treatment code is set for the output drive 26B by the output channel selection button 17H, the determination result in Step S119 is Yes, the process proceeds to Step S122, and the end lamp buzzer is not turned ON. Steps S104 to S119 are repeated for the other treatment codes, and steps S120 and S121 are executed after the steps are completed.

  In the above embodiment, each waveform storage area 22-1 to 22-N in the waveform memory 22 stores voltage waveforms continuously for 3 minutes, but the present invention is not limited to this. If the voltage waveform storage capacity of the waveform memory 22 is not sufficient, etc., the voltage waveform is stored for two or three equal times of the set time (3 minutes in the embodiment), and one set time is set. Thus, the voltage waveform may be read out and used twice or three times. FIG. 7 shows a case in which 3 minutes are divided into 3 equal parts, and the voltage waveform is read out 3 times per minute.

  In the above embodiment, the sampling frequency is 192 kHz and the number of quantization bits is 24 bits. However, this uses a so-called sound source chip for the waveform memory, and the upper limit is 192 kHz, 24 bits. The present invention is also applicable to cases where the frequency exceeds 192 kHz and 24 bits.
